'7 Claims. (Cl. 4--252) This invention relates to an improved pipe fitting which is especially adapted to be used with a stack hung blowout toilet bowl. The fitting is designed to be positioned within the wall of a building.

The conventional type of blowout bowl requires considerable pressure and volume of water for successful operation. In fiushing this type V of bowl a large volume of water under a relatively high pressure must be introduced to sweep the water through the bowl and upwardly over the water seal and thence through the discharge pipe. Pressure and volume alone are relied on. Consequently, the use of blowout toilet bowls have been limited to those places where volume and pressure are above normal requirements.

The present invention when associated with a stack hung blowout bowl operates efficiently on a greatly reduced pressure and volume than is required to operate the same bowl without the improved fitting. The pressure and volume required to operate the conventional type of blowout bowl with the improved fitting is below the pressure and volume normally delivered in residential sections.

The improved fitting of this invention now makes stack hung blowout bowls usable in residential localities where water pressure and volume are relatively low. The improved fitting when associated with a stack hung bowl permits operation thereof with either a tank or flush valve.

One of the principal objects of importance and advantage of the improved pipe fitting of this 39 invention is the provision of means for providing a siphon action for a conventional blowout bowl.

Another and still further important object of advantage resides in the provision of means which permit a number of fittings to be used 4 on various floors one above the other.

Still another object of importance is the provision of means for preventing large obstacles from entering the soil pipe portion of the fitting.

An additional object of advantage and importance resides in the provision of means whereby the improved fitting of the invention may be positioned in and form a part of a soil pipe line.

Additional objects of advantage and importance will become apparent as the following detailed description progresses, reference being had to the accompanying drawing, wherein Fig. 1 is a front elevational view of a pipe 55 fitting which embodies the invention.

Fig. 2 is a side elevational view thereof.

Fig. 3 is a top plan view of the fitting.

As shown in the drawing:

The reference numeral It indicates generally a soil pipe. This portion of the fitting is preferably of conventional size and shape. However, it will be obvious that the size and shape of the soil pipe member I0 may be varied to suit any particular requirement or desire.

Projecting outwardly from the .soil pipe ill closely adjacent the lower end thereof is a horizontal pipe [2 which provides a passageway into the interior of the soil pipe It. The pipe i2 extends substantially horizontal for a short distance and then turns upwardly and thence forwardly, as is clearly shown in the drawing. The pipe !2 is slightly restricted at the elbow where it turns upwardly, as is best shown in Fig. 1. The inner portion of the elbow projects into the pipe as indicated by the reference numeral I3 to provide a means for preventing the passage of large foreign obstacles into the horizontal portion of the pipe l2 and into the soil pipe I0.

Secured to the upper portion of the soil pipe Ill and extending downwardly parallel to said soil pipe and having its lower end operably connected to the pipe [2 is a vent pipe I l. The vent pipe 14 may be omitted where it is so desired. The use of the vent pipe I 4 on the lower installations of a multiple storied building prevents siphoning of the lower bowls when the upper bowls are flushed.

Positioned on the forwardly extending portion of the pipe I2 is a securing plate It. The securing plate i6 is secured to the vent pipe l4 and also to the pipe I2 by means of lugs l8, as best shown in Fig. 2.

Formed in the securing plate l6 preferably on opposed sides of the forwardly projecting portion of the pipe l2 are bolt receiving recesses 20.

Formed in the upper portion of the securing.

plate I6 is an aperture 22 which allows a water pipe to be extended therethrough to a bowl.

Projecting outwardly from the face of the securing plate I6 is a plurality of bosses 24 against which a bowl is adapted to be secured.

In the preferred embodiment of the device the entire structure comprises a single casting. However, it will be apparent that the improved fitting of this invention may be constructed of several associated parts without departing from the spirit or scope of the invention.

It will also be apparent from the foregoing disclosure that the improved fitting of this invention provides the downwardly extending leg of a siphon when the device is associated with a conventional blowout bowl.

Furthermore, it will also be apparent to those skilled in the art to which the device appertains that numerous changes and alterations in construction and design may be made all without departing from the spirit or scope of this invention. Accordingly, it is understood that the patent granted hereon is not to be limited to the preferred embodiment here disclosed nor in any other manner except as necessitated by the terminology of the appended claims when given the range of equivalents to which they may be entitled.

I claim as my invention:

1. In a pipe fitting, a soil pipe having an extension at right angles thereto, said extension being turned upwardly and thence forwardly to form the downwardly extending leg of a siphon, a supporting plate secured to the forwardly turned portion of said extension and parallel to the upwardly extending portion thereof, and a flush pipe receiving opening in said plate directly above the opening in said extension.

2. In a pipe fitting, a soil pipe having an extension at right angles thereto, said extension being turned upwardly and thence forwardly, a supporting plate secured to the forwardly turned portion of said extension and parallel to the upward turned portion thereof, a plurality of spacing bosses on the face of said supporting plate, and a vent member secured to the horizontal portion of the extension and extending upwardly therefrom.

3. In a pipe fitting, a soil pipe having an extension at right angles thereto, said extension being turned upwardly and thence forwardly, a portion of the interior of said extension intermediate the ends thereof being restricted, a supand means for extending a flush pipe through said supporting plate.

4. A pipe fitting comprising a soil pipe, a discharge pipe in operable association with said soil pipe, a vent pipe secured to said discharge pipe and extending upwardly, the upper end of said vent being secured to the upper end of the soil pipe, a bowl supporting member positioned on the upper portion of said discharge pipe, means for extending a flush pipe through said supporting member, and means for spacing a bowl from the face of said supporting member.

5. In a pipe fitting, a soil pipe having an eX- tension projecting outwardly at right angles thereto, a portion of said extension being turned upwardly and thence forwardly to form a downwardly extending leg of a siphon, a supporting plate secured to the forwardly turned portion of said extension and parallel to the upward portion, and a vent member secured to the horizontal portion of the extension at a point below the lower end of the downwardly extending leg of the siphon and extending upwardly therefrom, said supporting plate being secured to the vertical portion of said extension and to said vent.

6. In a pipe fitting, comprising three vertical pipes in spaced parallel relation, a passageway extending from the lower ends of two of said parallel pipes into the third pipe, the upper ends of two of said parallel pipes being joined, a bowl supporting plate positioned on the upper end of one pipe and joined to the intermediate portion of another pipe, and bowl securing receiving means formed in said supporting plate.

7. In a pipe fitting, comprising a plurality of vertical pipes in spaced parallel relation, said pipes comprising of a soil pipe, a vent pipe, and a siphon discharge pipe, the lower part of said discharge pipe being turned to the horizontal plane and attached to the soil pipe, the lower end of said vent pipe being attached to the horizontal portion of said discharge pipe, and a bowl supporting plate joined to said discharge and vent pipes.
